Using `github` while disabling `edDraftURI`

[plehegar]

Description of problem

https://respec.org/docs/#edDraftURI

says:

Note: it is strongly recommended that you don't publish Editor's drafts, and instead auto-publish your specification using the W3C's Echidna workflow.

Yet, https://respec.org/docs/#github says :

This automatically generates: .[..] edDraftURI

Those 2 statements seem to contradict each other.

URL to affected spec or repo:

https://github.com/w3c/pointerevents/blob/level3/index.html

What happened (e.g., it crashed)?:

edDraftURI: '',
github: "w3c/pointerevents",

Unless edDraftURI is present, respec generates one by default (due to our use of github). Yet, we don't publish an ED for that level, even if we have a GitHub repo.

Expected behavior (e.g., it shouldn't crash):

Ability to use github for GitHub feedback, while disabling the presence edDraftURI.

As a side, while

edDraftURI: ''

does the trick for now, you can't pass an empty string as a URL parameter <url>?edDraftURI= (eg to use with w3c/spec-prod/W3C_BUILD_OVERRIDE).
